<p>Dear Wien2k admins and users</p>
<p>I am using WIEN2k_21.1 on linux mint 21 (MATE 64-bit) mint code for apply external electric field to a two dimensional semimetal system. Unfortunatly, after following the userguide instructions, it seems that external electric has almost no effect on my electronic band structure.</p>
<p>I have tried various values of IFIELD paramater (30, 8000, 10000, 11000, 12000), but the expected splitting in the band crossing did not happen. I also tried a lot to reproduce the calculations in the results of the article (<a href="https://doi.org/10.1016/j.physe.2012.04.017" rel="noopener noreferrer noreferrer" target="_blank">https://doi.org/10.1016/j.physe.2012.04.017</a>) on bilayer graphene, but I failed to observe the reported spliiting after applying electric field.</p>
<p>my case.in0 input file for electric filed application:</p>
<p>TOT XC_PBE (XC_LDA,XC_PBESOL,XC_WC,XC_MBJ,XC_SCAN) <br>NR2V IFFT (R2V)<br> 18 18 216 2.00 1 NCON 9 # min IFFT-parameters, enhancement factor, iprint, NCON n<br>8000 0.3<br>8000 0.3</p>
<p>Your kind help is highly appreciarted.</p>
<p> Best Regards</p>
<p> Z.Nourbakhsh</p>
